US Retains Top Spot in Quantum Technology Patents While Europe Surges, Study Finds
The United States has maintained its status as the global leader in quantum technology development, holding the largest share of patent filings between 2020 and 2024. According to a new joint study by the European Patent Office (EPO) and the Organization for Economic Cooperation and Development (OECD), the US accounted for 31% of international patent families during this period. This metric tracks inventions protected across multiple countries, offering a reliable gauge of high-value innovation.
Despite holding the top spot, the American dominance in the field is showing signs of erosion. The US share of global quantum patents dropped significantly from 41% in the previous five-year timeframe. This decline comes as other regions accelerate their research and development efforts to close the technological gap.
Europe has emerged as the primary challenger, securing second place with a 25% share of global patent applications. This represents a dramatic increase from the mere 9% share the continent held in the preceding period. Within Europe, Germany stands out as the innovation engine, ranking fifth globally with 7% of all patent filings.
Following the US and Europe, Japan secured the third spot with 13% of the total share. China followed closely behind in fourth place, capturing 12% of the global patent market. The study highlights how the landscape is becoming increasingly competitive as major economic powers vie for technological sovereignty.
The report also sheds light on the specific areas driving this explosive growth. Quantum computing has overtaken quantum communication to become the most dynamic sub-sector, particularly since 2022. Overall, patent filings for quantum technologies have grown by an average of 20% annually since 2014, far outpacing the 2% average growth seen in other technology sectors.
However, the path to commercialization remains fraught with challenges, particularly regarding funding and supply chains. While European institutions are filing more patents, they still face a significant investment gap compared to their American counterparts. Approximately 60% of global investment in quantum startups flows into US companies, giving them a distinct advantage in bringing products to market.
The study further identified critical vulnerabilities in the global supply chain for quantum hardware. The production of essential components relies heavily on specific raw materials, such as industrial diamonds and specialized salts. Many of these resources are concentrated in a few countries, creating potential bottlenecks for future development.
Researchers also noted the exceptionally high barrier to entry for workforce talent in this sector. Unlike the broader tech industry, the quantum field is deeply rooted in academic science. More than half of all quantum startup founders hold a PhD, compared to just 10% of founders in other technology fields.
As the race for quantum supremacy heats up, nations are forced to balance domestic innovation with international cooperation. The shifting percentages suggest that while the US had an early head start, the next decade of quantum breakthroughs will likely be a much more global endeavor.
